چکیده

In this work we examine the user behavior of the National Center for Atmospheric Research’s (NCAR) archive. In particular we characterized user sessions and examined namespace locality of accesses within those sessions. Preliminary results suggest within a single session, repeat file accesses are uncommon, and that accessed files are localized within a small set of directories. This work provides a baseline and preliminary results for a more detailed future study.
